To all 107mm t may conce/fn.'

Be it lrnown that l, HARRY L. HUDSON, a citizen of the United States,and resident of the borough of Brooklyn, in the City and State of NewYork, have inrented'a new and useful Improvement in Sheet-Metal Boxes,of which the following is a specification.

The object of my. invention is to provide a sheet metal box inwhieh thetop member may be interloelred to the body of the bor;

View in side'elevation of the separate top member.

The body portion of the box shown herein comprises a lower tubularmembery 1 and an upper tubular member 2. rElie upper edge of' thelowermember l is permanently united to the lower edge of the upper tubularmember 2, as, for instance, by crimping the edges together.

The upper edge of the upper tubular member 2 is turned inwardly, asshown at 3, forming an inner annular shoulder at the mouth or the box.(The separate top member 4 has a depending flange 5 which is fitted tobe inserted within the mouth of the body portion of the box, the saidflangeA tting closely the inwardly turned upper edge of the uppertubular member 2. This flange is provided with means for limiting theentry o the top member into the upper tubular member, which means, inthe present instance, is shown as a peripheral external shoulder 6arranged to engage the upper edge or the tubular member 2 when the topmember is inserted into position.

rlie depending flange 5 of the top member 4- is further provided withmeans for interloelring the top member to the body portion of the box,which means is herein shown as one or more upwardly directed springtongues 7 pressed outwardly from the flange at the proper point to snapoutwardly under the inwardly turned upper edge 3 of the upper tubularmember 2,*when the top member 4: is inserted into its position.

F rom the above description it will be seen that a box is provided inAwhich the separate top member "may be interloclied .with the bodyportion of the box after the box has been filled and that any attempt onthe part of a person to remove the top member for. I

unlawfully relling the box or for any other purpose, will only serre tomore firmly loe-h the top member to the body portion of the esv box, asthe tongue or tongues 7 will be forced into'the space between theinwardly turned flange 3 and the wall of the upper tubular member 2.

It. is evident that slight changes may be vresorted to in the form,construction and arrangement of the'seyeral parts without departing fromtnespirit and scope of my invention; hence T do not wish to limit myself strictly thestructure herein set forth',

but

1. A sheet metal box comprising a tubular member having an inwardlyturned up# per edge and 'a separate 'top member having a dependingflange fitted toenter the tubular member, said flange being providedwith yielding means arranged to snap outwardly under the said inwardlyturnedupper edge of the tubular member for permanently locking the topmember against withdrawal. 1

2. A sheet metal box comprising e. tubular member haring anV inwardlyturned upper edge and a separate top member having a depending flangeiitted to enter the tubular member, said flange being provided withyieldingmeans arranged to snap outwardly under thesaid inwardly turnedupper edge of the tubular member for permanently leeking the top memberagainst withdrawal, the said Harige being further provided with meansarranged to engage the turned upper edgeV of the tubular member forlimiting the entry of the top member.

3. A sheet metal box comprising a tubular member having an inwardlyturned upper edge and a separate top member having a depending flangefitted to enter the tubular member, said flange being provided with'yielding means arranged to snap outwardly under the said inwardlyturned upper edge or the tubular member for permanently locking die topmember against withdrawal, the said Tiange being further provided with aperipheral external shoulder arranged to eniop ies

gage member for limiting tbe entry of 'the top the turned upper edge ofthe tubular membern Y el. A sheet metal box comprising :1 tubuler memberharing an inwardly turned upper edge and e seperate top member 'harvinga depending flange iitted to enter the tubular member, Seid lienge beingprovided with one or more upwardly directed spring tongues pressedoutwardly therefrom arranged to snap outwardly upper edgeof .ad tubularmember for permanently locking the top member against Withdrawal.

5. A sheet metal box comprising e tilbulnr member having en inwardlyturned upper edge and e. separate top member having e depending lzingelitted to enter the tubular member. eid [lange being provided with eneor mire upwardly directed spring` tongues pressed. euinmrdly therefromar ranged to snap entwerdly under' the in- 4` under the inwardly turnedVes my invention, I have werdly turned upper edgepf Said tubular memberfor permanently flocking the top member against withdrawal, the saidflange being further provided-With :i peripheral external Shoulderarranged toengage the tul billar member for limiting the entryvot' thetop member. 6. A sheet metal 'box comprising u lower tubular member7 :inupper tubular memberpermanently vunited thereto` and having en inwardlyturned upper edge and a seperate top member permanently intel-lockedwith the inwardly turned upper edge 'of the seid upper tubular member.

In testin'ieny,l that I claim the foregoing signed my name in presenceof two \vitnesses, this twentieth day'o November 1912.
